Topological susceptibility in Yang-Mills theory in the vacuum correlator method
arXiv:0705.4624 · doi:10.1134/S0021364007130012
Abstract
We calculate the topological susceptibility of the Yang-Mills vacuum using the field correlator method. Our estimate for the SU(3) gauge group, χ^{1/4} = 196(7) MeV, is in a very good agreement with the results of recent numerical simulations of the Yang-Mills theory on the lattice.
